本日接到保障在11g通過數據泵導入數據時報錯，ORA-39245，查詢文檔發現說明如下
[oracle@evenpc ~]$ oerr ora 39245
39245, 00000, "import job requires export dump file \"%s\""
// *Cause: A Data Pump IMPORT or SQL_FILE operation was being performed
// but not all of the files from the Data Pump export dump file
// set were included.
// *Action: Check the export log file and make sure all of the files that
// were exported are included in the current job. The import log
// file also lists the export names of the missing files.
用戶說導出給了一個文件，導入的時候死活導入不了。
檢查用戶導出操作命令如下：
expdp user/passwd directory=dump_dir dumpfile=test%U.dmp parallel=2 logfile=test.log schemas發現用戶用了parallel參數，導出的時候絕對不止生成一個文件，問題找到了，用戶導入的時候只導入了一個文件，就會報錯了。
修改下導入操作命令如下
impdp user/passwd directory=dump_dir dumpfile=test01.dmp,test02.dmp parallel=2 schemas=test logfile=test_imp.log問題解決。
